The World Boxing Organisation has announced Tszyu (16-0) will be next in line to fight for the world junior middleweight title should he get through Bowyn Morgan (21-1) on Wednesday.

If current champion Patrick Teixeira and No. 1 ranked challenger Brian Castano cannot make their fight by January 6, then Tszyu will fight for the WBO strap next.

But Tszyu is refusing to look any further than his Kiwi counterpart Morgan as they prepare to headline Sydney's first stadium fight since 2006.

"I'm not thinking about it yet because I've got one target in front of me, one victim that's trying to take it all away from me and I don't underestimate no one," Tszyu said.

"Every fighter's dangerous in their own way. Bowyn's dangerous. He's going to bring a tough fight so, Iook, I'm not underestimating him and once the fight finishes we can start talking about world titles.

"All the hard work is coming through. You don't get to this position overnight. It takes years and years so we're here now.

"It's been a lot of work throughout the years and I'm not going to let anyone to take it off me."

Yet across the Western Sydney Stadium ring come Wednesday night will stand Morgan, who has little time for the Tszyu fairytale.

"I've trained my butt off for this fight and I can't wait to get in there," Morgan said.

"I know the work's been done. I actually don't care too much about what everybody else is thinking. It's me in there and this is my opportunity.

"It doesn't go the full 10."

Tszyu says he is a better fighter than the one which disposed of Jeff Horn in a changing of the guard moment, so as for Morgan's prediction?

"He predicted it right, it doesn't go the distance," Tszyu said.

"I'm growing, I'm getting bigger and stronger. I'm getting better each day so this fight you'll see something different.

"Each fight I like to bring something new, something different and this fight you'll see little changes but you'll also see big changes as well."

The 26-year-old's manager Glen Jennings says the prospect of luring a world title fight to Sydney would be huge for the sport.

"It's only literally four years since Timmy turned pro and so to get the opportunity on the back of this Wednesday night is wonderful, it's something we hope we can grasp and bring here to Australia," Jennings said.

"And hopefully, maybe right here at [Western Sydney] Stadium. A world title fight of that magnitude would be tremendous.

"But we're realists. One step first, Bowyn Morgan is going to be in our way and we need to dispose of him on Wednesday and then we'll get stuck into the chat about the potential world title."
